MACHINIET FOR FOLDING PAPER.

To all cahomt'may concern.'

Be it known that we, C. PYLE WIGGINs, A. (H. NORD'YKE, and BENJAMIN STRAw- BRIDGE, all of the city of Richmond, in the prevents retraction of the paper.

.l erence being had to the annexed drawings,

making a part of this specication, in which-Y Figure 1, is a perspective view of our invention. Fig.'2 shows the contrivance which A, A, A, constitute a rectangular framework, as shown, permanently framed together in a suitable manner, and upon which is secured the metallic frame B, B, B; in

l the upper plate of this frame is a long slot f J k or opening, b, which is an entrance to a sort of throat composed of upright bars, b', b, standing in double ranks.

b, b, Fig. 2, represent part of another set of bars and another throat, at right angleswith b', b.

C, is afolding blade directed in its motion by guides in part E, (not shown). Blade, C, is operated by cords, c, c. It folds a sheet of paper in the middle when properly laid upon plate, B.

D, is also a folding blade which receives and folds the paper after it has been folded by blade, C. It is operated by cords, d, CZ.

The folding may be multiplied to any required number of times without any addition of machinery save an additional numy ber of blades, pulleys and drums, the drums 40' being placed upon the same shafts with those already shown.

F, is a flanged drum upon shaft, f. Upon one part of its periphery is coiled a portion of the cord, o, on the other part, a corresponding portion of cord c; but in an opposite direct-ion, so that as one is-coiled the other is uncoiled and vice versa.

G is a drum similar to F, with also an arrangement of cords, d, d, similar to cords, c, e.

f', g', are pinions upon the outer ends of shafts f and g, respectively.

H, is a lever swung in an adjustable fulcrum or pivot frame z'. At its lower eX- tremity is a toothed segment which actuates pinion, f. Its upper end passes behind cam wheel L, and is armed with a stud Z.

H, is a lever similar to H. It has also an adjustable fulcrum, j.

c', is an adjustable fulcrum to lever H. It receives lever, H, in a mortise through its body as shown, and retains itin position by means of a set screw. Upon its back is a small boss or stud which passes loosely through plate K so as to allow free lateral vibration of, z', but it is headed to prevent retraction.

y', is a device similar to K, is a plate which receives studs from fulcrums z', y'. It is adjustable by means of set screws at each end, as shown, in combination with fulcrums, i, y'. It affords a ready means of changing the position of the center of motion of lever, H H, thereby regulating the stroke of the blades, C, D, according to the size of the paper to be folded.

rPhe dotted lines, m show the shape of the flanges or cam upon wheel, L, which actuates levers, H, H. This cam is half eccentric and half concentric so that while one of the levers is in motion, the other is at rest.

Wheel, L, is borne upon a short shaft which has boXings upon the framework of the machine.

M, is a winch by which the machine is operated.

N, O, P, constitute a device by means of which the paper is prevented from retraciion with the blade after it has received a old.

N, is a sort of movable jaw pivoted near its middle as shown and held in position by a small spring.

O is a Xed jaw against which, N, may be made to grip the paper.

P is a lever with its center of motion upon bracket, p. One end of this lever is in contact with aw, N, the other presents an inclined surface across the path of blade- D. Bracket, p, is placed dia onally upon bars b 5; its shape is su 'ciently indicated in the ligure. As blade D enters the sort of throat in which the paper is folded it cornes in contact with lever P, pressing it outward thereby causing, N, to clamp the paper against O, and prevent its retraction.

Operation: Continuous rotation should be communicated to wheel L by means of the handle M. This causes an alternate action of the blades C, D. As already shown, when the blade C, has arisen from the slot, Z9, and is at rest awaiting the action of blade D. A sheet to be folded, is laid properly upon the plate B. Blade C, now descends upon the paper forcing it into the throat formed by uprights, b, and folding it evenely and smoothly its entire length. Blade, C, is now retracted, and while blade D is performing its work. Another sheet is laid upon plate B, blade C, again descends. And thus on continuously till the desired number is folded.

This machine is by no means complex in construction is not liable to wear or fracture, is easily adjusted to any requisite size of paper, and performs its work well. It

may be connected to a cylinder press and receive the papers directly from the y thus "ing an alternate movement of blades, C, D,

as set forth.

3. The combination of jaws yor clamps, N, O, and lever P, with blade, D, to prevent retraction of the paper. Y
